That's an isosceles triangle lying on its side. The base angles (on the left) are marked equal, so we know the sides opposite them are equal.
That means that . . . x+4 = 3x-8
Subtract 'x' from each side . . . 4 = 2x-8
Add 8 to each side . . . 12 = 2x
Divide each side by 2 . . . <em>6 = x</em>
$112
1-1/5=4/5
4/5 x 140 =112
hope this helps :)
The answer is 3ft because i know im in high schooland u have to find the legth
Answer:
a. 1/2
b. 5/3
c. 0
d. undefined
Step-by-step explanation:
Answer:
option 4.
16 square units
Step-by-step explanation:
as we do not have the measures of the sides, but if the points of the vertices with Pythagoras we can calculate the sides.
P = (2 , 4)
S = (4 , 2)
we have to subtract the values of p from s
PS = (4 - 2 , 2 - 4)
PS = (2 , -2)
by pitagoras h ^ 2 = c1 ^ 2 + c2 ^ 2
h: hypotenuse
c1: leg 1
c2: leg 2
PS^2 = 2^2 + -2^2
PS = √ 4 + 4
PS = √8
PS = 2√2
S = (4 , 2)
R = (8 , 6)
SR = (8-4 , 6-2)
SR = (4 , 4)
by pitagoras h ^ 2 = c1 ^ 2 + c2 ^ 2
h: hypotenuse
c1: leg 1
c2: leg 2
SR^2 = 4^2 + 4^2
SR = √ (16 + 16)
SR = √32
SR = 4√2
having the values of 2 of its sides we multiply them and obtain their area
PS * RS = Area
2√2 * 4√2 =
16
